Xa uqala ukukhangela abavelisi bentsimbi ye-ductile, into yokuqala oya kuyiqaphela kukuba mangaphi avakala ngendlela efanayo. Wonke umntu ubanga isatifikethi se-ISO, i-metallurgy ephucukileyo, kunye nokuhanjiswa ngexesha. Umahluko wangempela, into ehlula iqabane elithembekileyo kumthengisi ovele athulule isinyithi, ayikho kwincwadana. Kukwiinkcukacha ezingabonakaliyo zolawulo lwenkqubo, ukuphathwa kwenguqu engundoqo kwi-2 AM, kunye nokuzimisela ukubuza umzobo wokunceda umthengi. Abathengi abaninzi kakhulu bafumana ukulungiswa kwixabiso ngekhilogram nganye okanye izithembiso ezingacacanga zomgangatho ophezulu, ziphosakele igrit yokusebenza eqinisekisa ukuba ukuphosa kuya kwenza okanye kusilele ebaleni.
INiche yeShell Mold kunye nalapho Intsimbi yeNsimbi ingena khona
Ayizizo zonke iivenkile ezinokwenza yonke into kakuhle. Eso sisifundo esifundwe kabuhlungu. Ndibone iinkampani zizama ukunyanzela inkqubo engahambelani nejometri okanye izinto. Umzekelo, ukugxila kwethu kwi-QSY kudala kusenzeka iqokobhe ngundo ukuphosa. Kwizinto ezithile zentsimbi ye-ductile-cinga imizimba yevalvu esebenza ngoxinzelelo lwehydraulic, izindlu zegiya ezidityanisiweyo, okanye izibiyeli ezifuna umphezulu ogqwesileyo wokugqwesa kunye nokuhambelana komgangatho-ihlala ilingana ngcono kunesanti yemveli eluhlaza. Ukunyaniseka kwe-mold kuvumela iindonga ezincinci kwi-ductile iron ngaphandle kokuvalwa okubandayo, okuyintloko eqhelekileyo. Kodwa asiyombumbulu yomlingo. Ixabiso lepateni yokuqala ephezulu lithetha ukuba iyavakala kuphela kwimitsi ephakathi. Awunakusebenzisa isigqubuthelo somngxuma omnye, ngokucacileyo.
Kulapho kuboniswa khona iminyaka engama-30 kumdlalo. Ayikokuba nomgca wokubumba weqokobhe; imalunga nokwazi ukuba ungamkhokelela nini umxhasi ukuya kuyo ngenxalenye yawo yentsimbi, kwaye nini ukuthetha ngokunyanisekileyo enye inkqubo (mhlawumbi nakwenye ivenkile) ingabiza kakhulu. Siphulukene ne-odolo enokubakho kube kanye ngokucebisa ukuba kwenziwe utyalo-mali kwindawo entsonkothileyo kakhulu, enodonga olucekethekileyo olungenasisihla endaweni yokuzama ukuyinyanzela kwinkqubo yethu yeqokobhe le-ductile. Umxhasi wabuya kwiminyaka emibini kamva kunye neprojekthi eyahlukileyo, ethemba loo ngcebiso. Loo mbono yexesha elide ibaluleke ngaphezu kokuthengisa ngokukhawuleza.
Ukutshintsha kwezinto kubalulekile kakhulu. Ukugalela i-iron ductile kwi-shell mold kufuna umdaniso owahlukileyo kunokugalela intsimbi engwevu. Unyango lwe-magnesium ye-nodularization luchaphazela ulwelo kunye nokuziphatha kokuncipha. Ukuba i-Foundry ayihlengahlengisi i-gating yayo kunye nenkqubo yokunyuka ngokukodwa kwi-ductile kwi-mold echanekileyo, uya kufumana i-shrinkage porosity kumacandelo abalulekileyo. Ndibone iinxalenye zidlula uhlolo olubonakalayo kodwa zisilela phantsi koxinzelelo ngenxa yokuba ukuqina akuzange kulawulwe ngokuchanekileyo kwizinto eziphathekayo. Koku kuhlangana kwenzululwazi yezinto kunye nobuchule benkqubo obuchaza ingcali yokwenyani.
UMatshini we-CNC: Umthetho weSibini ongaxoxiswanga
Nanku umngxunya omkhulu: ukufumana izinto ezenziweyo kumenzi omnye kunye noomatshini kwenye indawo. Kwi-iron ductile, ngakumbi amabanga afana ne-65-45-12 okanye i-80-55-06, isibonelelo somatshini kunye nemeko yoxinzelelo lwendalo yokuphosa idityaniswe ngokungenakuhlukaniswa. Ukuba umachini akaqondi ukuba inxalenye yagalelwa kwaye yapholiswa njani, banokungena kwiimeko ezibuhlungu-incoko yesixhobo, iindawo ezinzima ezingalindelekanga, okanye ukugqwetheka emva kokusikwa kokuqala kukhuphe uxinzelelo lwangaphakathi.
Yiyo loo nto yethu idibeneyo CNC Machining isakhono asikokongeza nje ixabiso; yimfuneko yolawulo. Simachine oko sikuphosayo. Le loop ivaliweyo isivumela ukuba sicofe kwinkqubo yokuphosa kunye nesigqibo sokugqibela. Umzekelo, singongeza isitokhwe esincinci kubuso beflange sisazi ukuba ubushushu obuthile buthanda ukutsala indlela ethile, siqinisekisa ukuba sinokuyicoca ukuya kuthi ga ngaphandle kokukhupha. Iphelisa umdlalo wokutyhola phakathi kwe-Foundry kunye nevenkile yomatshini, eyindleko enkulu, efihliweyo kubathengi.
Imeko ebonakalayo yayiyindlu yempompo kwi-ductile iron 450-10. Umxhasi wayefuna ukunyamezela i-H7. Ukuba iphoswe kwaye ithunyelwe ingenziwanga, nangenkqubo yethu yeqokobhe, ukufezekisa oko ngokungaguquguqukiyo akunakwenzeka ngenxa yokuqhutywa okuncinci okungundoqo okanye ukwahluka kwe-thermal contraction. Ngokwenza umsebenzi okruqulayo ngaphakathi kwindlu kwii-horizontals zethu ze-CNC, sinokufaneleka ukuphosa kuqala, sisekwe ngokusekwe kweyona datum ye-as-cast, kunye nesiqinisekiso sokuzala. Inxalenye yayingekokuphosa nje; yayisele igqityiwe, ilungele ukudityaniswa. Oku kudityaniswa ngokuthe nkqo kuko okujika umthengisi abe liqabane. Ungayibona le ndlela kwipotfoliyo Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), apho ukuphosa kunye nomatshini kuboniswa njengenkonzo edibeneyo, ezalwa kumashumi amathathu eminyaka yokusombulula ezi ngxaki zichanekileyo.
Iincoko Zezinto Ezingaphaya Kwentsimbi
I-iron ductile ngokwayo ayiyona i-monolithic. Amabakala asemgangathweni sisiqalo nje. Iincoko zangempela zenzeke xa uyilo lufuna into ethile ekupheleni kwemvulophu-amandla aphezulu okudinwa, inkonzo ephezulu yokushisa, okanye ukuxhathisa ukunxiba. Apha kulapho umsebenzi wethu oneengxubevange ezikhethekileyo ezifana neze-nickel-based wazisa umsebenzi wethu we-iron ductile. Ukuqonda indlela i-alloys eziphatha ngayo phantsi kobushushu kunye noxinzelelo kudala indlela ethe kratya nakwizinto eziqhelekileyo.
Umzekelo, besineprojekthi yonxibelelwano lwecompressor enzima. Inkcazo yokuqala yayiyintsimbi ye-ductile 500-7. Ngokusekelwe kwidatha yomthwalo oguqukayo, sityhale umva. Sicebise ibakala le-600-3 kunye nolawulo olungqongqo lwepearlite kunye ne-anneal yokunciphisa uxinzelelo ngaphambi komatshini. Iindleko ezongezelelweyo zazincinci, kodwa into yokhuseleko kunye nobomi bokukhathala buphuculwe kakhulu. Umxhasi khange ayithathele ingqalelo; bachaza nje ibakala elifanayo. Umenzi ogcwalisa iiodolo nje ebeya kuphosa i-500-7 kwaye aqhubele phambili. Umvelisi otyale imali kumsebenzi wenxalenye kufuneka abe neengxoxo eziphathekayo.
Obu buchule bukwanceda xa ezinye iindlela zifuneka. Ngamanye amaxesha, emva kokuphonononga uyilo lokutya okuphezulu okanye ubushushu, sinokucebisa ukuba nentsimbi ephezulu yentsimbi ayisiyiyo impendulo eyiyo kwaye ibhekiselele kwindawo. intsimbi engenasici utyalo mali endaweni. Ukuba nephalethi yemathiriyeli ebanzi-ukusuka kwiintsimbi kunye neentsimbi ukuya kwi-cobalt kunye ne-nickel alloys-ithetha ukuba ingcebiso yinjongo, ayiqhutywa yinto ekwiziko lethu ngaloo mini. Kwakha ukuthembana.
IiNqobo ezisemgangathweni zoMgangatho
Umgangatho ayisosiqinisekiso edongeni. Luthotho lwezenzo zesiqhelo, ezingqongqo. Kwi-iron ductile, iqala nge-makeup yentlawulo kwisithando somlilo-ukulawula izinto zokulandelela ezifana ne-titanium kunye ne-lead engonakalisa i-nodularization. Yinkqubo yasemva kokuphoswa: ukudutyulwa kufuneka kube ndlongondlongo ngokwaneleyo ukuze kucoceke kodwa kungavuli umphezulu, okunokubakho ukugquma iziphene. Luhlolo lwedayi eyi-100% kubuso obunoxinzelelo, hayi nje isampulu yokukhangela.
Ndikhumbula ibhetshi yemizimba yevalvu apho ukufundwa kwe-spectrograph kubonise ukufiphala kwe-magnesium ngokukhawuleza kunokuba bekulindelwe. Ikhemistri yayisebuchwephesha ngaphakathi kwe-spec, kodwa imeko yayingalunganga. Sabuphelisa bonke obo bushushu—isigqibo esasibiza imali eninzi. Idatha yacebisa ukuba inani lamaqhuqhuva linokuba sezantsi, oko kubeka emngciphekweni ukuncipha kokudumba. Yayisisiphene esingabonakaliyo; Amalungu ayenokuthi aphumelele uvavanyo lwe-tensile kwikhuphoni, kodwa i-microstructure kumacandelo ashinyeneyo inokuba sengozini. Nantso ikhwelo lokugweba ohlawula ngalo: ukuzimisela ukufunxa ilahleko ukuthintela ukusilela kwentsimi.
Enye into eyinyani lucwangciso. Ukuphosa okugqibeleleyo akunamsebenzi ukuba yonakele kwindlela yokuhamba. Ukupakishwa kweentsimbi ze-ductile, ezinokuthi zibe brittle xa kuthelekiswa neentsimbi zentsimbi, bubugcisa. Sisebenzisa iikhreyithi zeplywood ezenziwe ngogwebu kwiimo ezintsonkothileyo, hayi nje ukujulwa kwibhokisi enezityali zomthi. Le ngqalelo kwinyathelo lokugqibela yinxalenye yenkqubo yokuvelisa, kakhulu. Zezi nkcukacha zokusebenza, kude nobuhle besinyithi esinyibilikayo, ezichaza umntu onobuchule i-ductile iron casting umenzi.
Ukukhangela iqabane eliLungileyo, hayi nje ixabiso
Ke, uyinqumla njani ingxolo xa uvavanya abavelisi bentsimbi ye-ductile? Musa ukucela nje ukucaphula. Cela isivuno sabo esiqhelekileyo sokutyisa kwindawo efanayo. Buza ukuba balawula njani ukuqina kokungunda kwisanti okanye inkqubo yeqokobhe labo. Cela ukubona isampulu yeNgxelo yoHlolo lweNqaku lokuQala, hayi nje isampulu emenyezelayo. Iimpendulo, okanye ukuthandabuza, kuya kukuxelela yonke into.
Inkampani efana ne-QSY, eneengcambu zayo ezinzulu kuzo zombini iqokobhe ngundo kwaye utyalo mali, izisa i-process-agnostic perspective kwi-ductile iron. Ayikokuthengisa indlela enye; imalunga nokufaka ekunene kwibhokisi yezixhobo. Loo mbali, eneenkcukacha kwisiza sabo kwi tsngtaocnc.com, iguqulela ukusombulula iingxaki. Kusenokwenzeka ukuba sele bedibene kwaye bawusombulule umba owuyilwayo ngoku.
Ekugqibeleni, ubudlelwane kunye ne-Foundry yintsebenziswano yobugcisa. Ezona ziphumo zihle zenzeka xa umenzi eziswa kuphononongo loyilo kwangoko, xa banokucebisa ngee-engile zokuyila, ubukhulu bodonga obufanayo, kunye nemigca yokwahlula egqibeleleyo yokushwabana okuthe ngqo kwentsimbi ye-ductile. Injongo ayikokufumana nje ibhokisi yokuphosa. Kukufumana icandelo elithembekileyo, elisebenzayo elisebenza ngaphandle kokukhutshwa, lithathwe kwiqabane elicinga lonke uhambo olusuka kwintsimbi etyhidiweyo ukuya kumgca wakho wokuhlanganisa. Leyo yeyona metric yokwenyani yesakhono somenzi, kude ngaphaya koko nakuphi na ukukhangela kwegama elingundoqo kunokutyhila.
